Dwayne Johnson is hard at work promoting Hercules, and his latest stop on the tour was The Tonight Show Starring Jimmy Fallon. As you might suspect, it wasn't just any ordinary visit. The two showed off some sweet workout videos from the '80s and the '50s, with a pair of instructors that just happen to look like them. Turns out The Fungo Brothers were responsible for a number of fitness breakthroughs, they just never got the proper credit. These are pretty great, especially when Johnson and Fallon spout catchphrases like "You gotta hustle for the muscle" and "This is not a workout, this is a revolution."
Obviously you need to see them also invent their own version of the infamous Shake Weight, as well.
